Finished 80% cast receiver!!!!!!! by hand

Hi

As I posted below I have completed a 70-80% receiver blank by century, I did this build by hand tools, these included a dremel, drill (cord), series of files-flat and round fine to bastard, levels, taps, cutoff wheels(stock up), grining stones, heavy vise. no milling machines no lathes or drill press. blueprints and downloaded posts by others from roderus

I will post the pictures in a few days, I have not cut the charging handle slot because I may relocate the charging handle.

this build should fire and feed fine. I am going to the range this week with a sub-caliber device 32acp in 308 adapter to fire function test. then the following week weak reloads very weak reloads

I loaded 1 weak reloads into the chamber. pulled the bolt catch and she locked up fine, with a coathanger and gun rest. I pulled trigger and low and behold no blown receiver, no cracks no deforms of any kind and I didn't loose any JB

but the primers came out and out the bottom of the mag well FLAT, case didn't eject ( gas valve not set) the neck was fire formed for a new caliber

Yes I know I am a smith excessive headspace and no I didn't headspace before hand.( bad habit building AK's) I will have to thread deeper about a half turn

To all my non friends here I was not hurt sorry to disappoint you!!!! you know who you are

when I loaded the 5 round in the mag ,she locked up tight, the pressure was high enough to blow the bottom of austrian mag out got to get that gas valve set

As of now I am the only person to have build a 70% FN FAL to fire function on all the sites I have checked

I have not heat treated the receiver as of yet, I was very concerned about this constant reference to blowing up the receiver from the beginning( I mean since 2003 when the first attempts were made to work these up over at RODERUS)
In fact some pictures for this build can be found in the FAL build section on roderus.

back to the heat treatment, after 5 shots of weak 308 there were no cracks, believe it maybe like the AK the barrel and bolt take the beaten, and yes 308 is hotter than 7.62 X 39mm
ok back to your question, bob at (a well known 80% receiver company) offered to assist me there, he nows of a facility to handle the project ( personnally I think its him)
post shooting examination revealed the jb touch up in the feeding ramp area was still in place I am wondering about the heat treatment

also two things to look out for the front of the casting is off to the left a bit. this must be compensated for.
also the feeding ramp is going to be a problem as are factory finished century receivers ( some rounds feed into the barrel base instead of the chamber. this is a common complaint on the fal files

That's pretty cool! I know these need the heat treat based on the threads I've read, and let's not forget DSArms' treatment of the issue. I think they had some blow-up pics on their site, but I don't really remember that far back.

Where do you find the castings these days? I saw one at a gun show one time, but that's the only one I've seen.
